Abstract

The patent relates to including the radiative power losses of the motor block and generator in the heating circuit of a multi-unit district heating power station (MDHPS), which is fitted with internal combustion engines, by means of a heat pump installed in the machine room. According to the invention, this heat pump can also be retrofitted.

Description

Blockheizkraftwerke, die gas-, benzin- oder dieselmotorisch angetrieben sind, werden heute zur dezentralen Stromversorgung mit Generator im Inselbetrieb oder Verbundbetrieb so ausgerüstet, daß einerseits die Kühlwasserwärme des Motorblocks über einen Wasser-Wasser-Wärmetauscher und andererseits die Abgas­ restwärme über einen Gas-Wasser-Wärmetauscher dem (Gebäude-)Heizkreislauf zu­ geführt wird.Combined heat and power plants powered by gas, petrol or diesel engines, are becoming a decentralized power supply with generator in island operation or Verbundbetrieb equipped so that the cooling water heat of the Engine blocks via a water-water heat exchanger and on the other hand the exhaust gas Residual heat via a gas-water heat exchanger to the (building) heating circuit to be led.

Die erreichten Wirkungsgrade als Verhältnis der gewonnenen elektrischen Energie zuzüglich der Heizenergie bezogen auf die eingesetzte Primärenergie (Öl, Benzin, Gas) liegen dabei über 60%. Bisher gehen jedoch die Abstrahlungsverluste des Motorblocks und die Verlustwärme am Generator verloren.The efficiency achieved as a ratio of the electrical energy obtained plus the heating energy based on the primary energy used (oil, petrol, Gas) are over 60%. So far, however, the radiation losses of the Engine blocks and the heat loss at the generator lost.

Der Erfindung liegt die Aufgabe zugrunde, die im Maschinenraum entstehenden Strahlungsverlustleistungen von Motor und Generator dem Wärmeverbrauchskreis­ lauf zusätzlich zuzuführen, da diese ca. 20% der Wellenleistung betragen können.The invention is based on the problem arising in the machine room Radiation losses from the motor and generator to the heat consumption circuit feed in addition, since these amount to approx. 20% of the shaft power can.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß in den Maschinenraum eine Luftwärmepumpe integriert wird, die die Strahlungswärmen im Verdampfer aufnimmt und auf höherem Niveau am Kondensator an den Heizkreislauf abgibt, wie in Abbildung 1 dargestellt.The object is achieved in that an air heat pump is integrated into the machine room, which absorbs the radiant heat in the evaporator and releases it at a higher level on the condenser to the heating circuit, as shown in Figure 1 .

Die Erfindung kann auch dazu genützt werden, bestehende BHKWe mit einer solchen Wärmepumpe nachzurüsten. Der Gesamtwirkungsgrad als Verhältnis vo eingesetzter Primärenergie aus den Heizwerten zu genutzter Energie als Strom und Wärme steigt dabei auf ca. 95%.The invention can also be used to combine existing CHPs with such Retrofit heat pump. The total efficiency as a ratio of the used Primary energy increases from the calorific values to energy used as electricity and heat thereby about 95%.
